Application lcd September 9, 1925. Serial No. 55,236.

My invention relates to improvements in organs, and more Aparticularly has reference to a compact form of instrument adapted thereof in dotted outline. tailed perspective v1ew ofthe pivotal shde for use in the home, requiring less space than some of the modern'types of upright pianos'.

'In the accompanying drawings, I have illustrated in Fig. 1 a suitable form of organ in perspective, parts being broken away, the same embodying an application ofvmy. 1nvention. Fig. 2 is another perspective view, parts broken away, illustrating the folded position ofthe pedal board and mountmg Fig. 3 is a demounting of the pedal board.l Fig. 4 is a view upon an enlarged scale, partly in c ross section, illustrating the tablet or dommo form of pneumatic control.l Fig. 5 illustrates upon an enlarged scale, in perspective, parts being broken away, a suitable form of electric switch for the motor, controlled by la similar tablet or domino form of operating mechanism. Fig. 6 illustrates in vertical section, part of the interior of the organ showing the detachable mounting of part of the mechanism thereof and the pedal connections, and Fig. 7 illustrates in cross section, upon an enlarged scale, a detail of the reed mechanism.

1 is the outer frame of the organ, and 2 the foot pedal frame which, it will be observed, is provided with pins 3 at opposite sides, the same adapted to slide in slots 4 in the L-bracket -5 secured within the base of the frame, so that when not in use, the foot pedal board can be pulled out in the position shown and then lifted vertically beneath the keyboard of the organ out of the way as shown in'Fig. 2. When lowered in position for playing, as shown in Fig. 1, it is pushed inwardly so that the foot pedal rods 26 extend above the levers 6, for operating the same.

7 indicates an electric motor having a pulley 8 upon which is mountedthe straps 9, 10, for operating the pumps 11at opposite sides in the bottom of the case, and 12 is the swell crescendo pedal. 13 is the shutter cover of the pedal chest which may be opened by operating the hooks 14, thus c'onveniently exposing the same for inspection, repair, etc. 15 indicates the wind channel, and 16 the detachable bellows upon which the wind channel 15 is mounted. 27 indicates wooden* brackets secured upon the in-'- screws or other suitable means 28. These serve to support the wind channel 15 which` is also provided with brackets 29,29', retaining the detachable bellows 16. thereon,

A`so that by removing the brackets 29, the

detachable bellows 16 may be removed and the Wind channel 15 may also slide out through the back of the organ frame from the brackets 27. 17 is a side wind channel, and 18, 19 the reed chests in the topof theV case the reeds thereof being indicated'by the reference character 30. 20, 21, are the two decks of keys common to a two manual organ, and 22 indicates a pneumatic connected to the rod 23, which in turn is controlled by the stop. 24: indicates an electric switch for controlling the motor 7 and this is preferably operated through the medium of a rod 34 connected to a stop' 32 in the front of the casing above the keys. The switch is preferably of the well known push button variety, the button thereof being represented by the spindle 33, which is pivotally connected to a bar 34', pivotally mounted at 35, upon the bracket 36, and pivotally connected at the opposite end to the link or hook 37, which in turn is pivotally mounted upon the stop 32, as shown, said stop being ivotally mounted on the pin 38, so that w en the front or tablet of the stop 32 is pulled out at the top, it pushes the button 33 of the switch in, and when pushed in at the top or pulled out at the bottom, it pulls the button 33 out, thus cutting in or out the current to the motor. This front easing is entirely removable for giving convenient access to the interior parts, and the same applies to a panel board adapted to fit into the frame at 25, which is removable for access to the interior of the organ beneath the keyboard.

This arrangement of the parts facilitates convenient access to all parts of the organ almost instantly, and thus very materially reduces the time required for cleaning and making repairs, while at the same time it cheapens the construction of the instrument without impairing the quality of the same.

Of course it will be understood that various modifications may be madein the construction and arrangement of parts without departing from the spirit of the invention as claimed. v
